Why bin/rails command to start rails server and not rails server command?

Treehouse TeacherWe encourage everyone to use bin/rails rather than just rails because that loads the rails executable from within the bin/ subfolder of your app, ensuring you get the correct version. If you run rails all by itself, that could run any rails executable anywhere on your hard drive. (Well, anywhere that's in your $PATH environment variable.) That will work fine if you only have one version of Rails installed, but some systems may come with older versions of Rails pre-installed, and you don't want to run one of those by accident.
(BTW, bin/rails by itself won't do anything, but bin/rails server will run the server. Also, don't put a slash at the start: /bin/rails will look for a "bin" folder at the root of your hard drive, which probably doesn't exist. bin/rails, however, will look in the current folder.)
